Methods and compositions using a combination of zwitterionic surfactants and gemini surfactants as diversion agents

摘要

A wellbore fluid may include a gemini surfactant, a zwitterionic surfactant; an activator, and an aqueous base fluid. The gemini surfactant may have a structure represented by formula (I):; where R1 is a C1-C6 hydrocarbon group or a monovalent cation, R2 is a C1-C10 hydrocarbon group, m is an integer ranging from 1 to 4, n is an integer ranging from 8 to 12, and X is a monovalent anion.
